22	!- Some confusing vocabulary in this code !
23	!- =========================================
24	!-
25	!- A REGULAR grid is a grid which is i,j indexes
26	!- and thus it is stored in a 2D matrix.
27	!- This is opposed to a IRREGULAR grid which is only in a vector
28	!- and where we do not know which neighbors we have.
29	!- As a consequence we need the bounds for each grid-cell.
30	!-
31	!- A RECTILINEAR grid is a special case of a regular grid
32	!- in which all longitudes for i constant are equal
33	!- and all latitudes for j constant.
34	!- In other words we do not need the full 2D matrix
35	!- to describe the grid, just two vectors.
